Ok, ok, there's this misconception that somehow the Oxygen bubbles increase O2 levels. They increase the O2 levels by the surface agitation they create. Not because you are fizzing gas in the water. O2, as far as I know, is less soluble in water than CO2.

You may run the airstone at night, if you want to, but that will not save your fish during the day.

Lol.

Funny enough I was recently reading an article about air stones and it mentioned all it does is move water.

So even still I'll try that and use the fx5 once again solely for co2/filteration.

Many thanks all.

Lol, you said the same thing as me but in reverse

Wouldn't this emulate why some people believe that their best growth comes from water change day?

The water that you get from tap has a lot of dissolved CO2 in it so not necessarily. But hey if you are seeing nice growth and little algae, keep doing it. We don't know how much light you actually have so you might have 70 PAR or 5. That will determine how much CO2 you need for the most part.

If I used less Co2 I would have to cut the light because I would be Co2 deficient.

I believe I have (up until the air stone) a severe o2 deficiency.

(due to glass and canopy)

I think both you and daniel just said the same thing haha. You are correct that light drives the CO2 demand by plants. I would advise against the airstone during the day since you will be degassing CO2 quite a bit. What you can do if you don't have a wet/dry filter is to increase surface agitation or decrease your light as you said. This can be done by a small fan, raising filter output, powerhead pointed up. Just try not to break the waters surface too much.

CO2 does not force you to increase light if we're talking about plant growth. It's the other way around. Also, from the fish's perspective, the O2 produced by the plants will not keep them from dying if you go over board.

Sorry I think I'm not getting what your saying.

+1 on the fan.

I would assume if you increased the CO2 bubble rate to compensate you could do that. I would just install an exhaust fan to exchange the air under the canopy, an added benefit would be removing the heat from the lights.

Now that's an idea!

Maybe a project for the summer!

But for now I guess I'll see how it goes unless someone chimes in and goes noooooiooo! Lol.

Ok thanks.

The problem is if I dose less Co2 I would have to cut back on light and my aim is to have a high tech tank.

The 'canopy' also doubles as my lighting system.

So, you're drinking and taking antibiotics at the same time

CO2 is a highly unstable gas dissolved in water. Surface agitation created by the bubbling will make the CO2 gas off.

If you want to keep things in check, dose less CO2. In my opinion, a canopy is more of a design thing than a functional component useful to an aquarium.

air stones (o2) in conjunction with co2

Hi,

Is it THAT terrible to have an air stone going whilst injecting co2?

Reason why I ask is because my aquarium has a glass lid with a wooden canopy on top.

Which causes trouble getting o2 in there.(poor gas exchange)

I can't remove the lid because the wooden canopy get wet via evaporation.

So I guess the question is if I can still get sufficient Co2 in there is this method ok?

I'm on the second day of this and in 18 months of converting my tank to a planted one its the first time I'm getting pearling.
